Detailed Description

The embodiments described below are merely one of various embodiments of the present disclosure. The embodiments of the present disclosure are not limited to the following embodiments, and may include embodiments other than these embodiments. The following embodiments may be variously modified according to design or the like without departing from the scope of the technical idea of the present disclosure.

(embodiment mode 1)

(1) Summary of the invention

As shown in fig. 1, the monitoring system 100 of the present embodiment includes a collection unit 712. The collection unit 712 collects monitoring information on the usage state of the monitoring target including the plurality of circuit breakers 2 housed in the distribution board 1.

In the distribution board 1 of the present embodiment, a main breaker 3, a plurality of branch breakers 4, a vibration-sensitive breaker 5, and a communication breaker 6 are housed as circuit breakers 2. The switchboard 1 does not necessarily have to house the vibration-sensitive breaker 5 and the interconnection breaker 6 as the circuit breaker 2, and can be omitted as appropriate.

Here, the main breaker 3 has a detection portion 32 for detecting electric leakage. When the detection unit 32 detects an electric leakage in the circuit connected to the main breaker 3, the main breaker 3 performs a breaking operation of breaking the circuit. The wiring system of the distribution board 1 according to the present embodiment is, for example, a single-phase three-wire wiring, and the detection unit 32 may have a function of detecting a neutral-out state in the single-phase three-wire wiring, or the main breaker 3 may perform a breaking operation when the detection unit 32 detects the neutral-out state. The detection unit 32 may have a function of detecting an inrush current generated by a lightning strike or the like, or the main breaker 3 may perform a breaking operation when the detection unit 32 detects the inrush current.

Each of the plurality of branch breakers 4 has a detection unit 41 for detecting an overcurrent such as a short-circuit current or an overload current. When the detection unit 41 detects a state where an overcurrent flows through the circuit to which the branch breaker 4 is connected, the branch breaker 4 performs a breaking operation for breaking the circuit.

The vibration-sensitive breaker 5 includes a vibration-sensitive sensor 51 for detecting vibration applied to the switchboard 1 due to an earthquake or the like. When the vibration sensor 51 detects vibration of a magnitude exceeding a predetermined reference value, the vibration-sensitive breaker 5 performs a breaking operation for breaking the circuit.

The interconnection breaker 6 is connected to a distributed power supply 21 such as a solar power generation system, a fuel cell system, or a wind power generation system. The tie breaker 6 is electrically connected between the secondary-side circuit of the main breaker 3 and the distributed power source 21. The tie breaker 6 is used to interconnect the distributed power source 21 with the system power source 20 or to disconnect the distributed power source 21 from the system power source 20. The interconnection breaker 6 has an electric leakage detection function for detecting electric leakage, for example. When the leakage detecting function of the interconnection breaker 6 detects leakage in the circuit connected to the interconnection breaker 6, the interconnection breaker 6 performs a breaking operation of breaking the circuit, and disconnects the distributed power source 21 from the system power source 20.

In this manner, in the circuit breaker 2 having the breaking function, when an abnormal event is detected, the circuit is broken. Here, the abnormal condition refers to at least one of a state in which an abnormal current such as a leakage current or an overcurrent flows, a state in which an abnormality such as a leakage, a short circuit, or a neutral-line phase loss occurs in a circuit connected to the circuit breaker 2, and an occurrence of an earthquake or a lightning stroke.

In the present embodiment, the collection unit 712 collects monitoring information on the usage state of the monitoring target including the circuit breaker 2. Here, the monitoring target of the monitoring system 100 includes at least a plurality of circuit breakers 2 housed in the distribution board 1. The monitoring target may include a load such as an outlet 22 (see fig. 1) electrically connected to the circuit breaker 2 or electrical devices 23 and 24 (see fig. 1). That is, the collection unit 712 also collects information on the outlet 22 provided outside the distribution board 1. The collection unit 712 also collects information on the operating states of the

electrical devices

23 and 24 electrically connected to the circuit breaker 2.

Therefore, the monitoring information on the use state of the monitoring target includes at least one of cutting information on the cutting operation of the circuit breaker 2 having the cutting function, information on the degree of deterioration of the circuit breaker 2 over time, and information on the load electrically connected to the circuit breaker 2, for example.

The cutting information includes, for example, at least one of information (hereinafter, also referred to as status information) indicating whether or not the circuit breaker 2 has performed a cutting operation, and cutting cause information on an abnormal event that causes the circuit breaker 2 to cut the circuit. The cutting cause information includes, for example, detection information of the current measuring device 8 (current sensor) that detects the current flowing through the circuit breaker 2, detection information of the leakage detecting unit (detecting unit 32) included in the circuit breaker 2, detection information of the neutral line open-phase detecting unit included in the circuit breaker 2, and detection information of the earthquake sensor 51 for detecting an earthquake, which is housed in the distribution board 1. Therefore, the interruption information includes at least one of the detection information of the current measuring device 8 (current sensor), the detection information of the leakage detecting unit (detecting unit 32), the detection information of the neutral-line open-phase detecting unit, and the operation information of the interconnection breaker 6. The circuit breaker 2 is not limited to the function of breaking a circuit triggered by the occurrence of leakage, overcurrent, neutral phase loss, earthquake, or lightning, but may be a function of breaking a circuit triggered by the occurrence of another event. The contents of the disconnection information can be changed as appropriate in accordance with the fact that the disconnection function has triggered the disconnection of the circuit.

The load information (hereinafter also referred to as load information) is information relating to the operating state of the load (for example, the receptacle 22 and the electrical devices 23 and 24) electrically connected to the circuit breaker 2. The load information includes, for example, a measurement value of a temperature sensor provided inside the outlet 22, error information regarding an abnormality occurring in the

electrical devices

23 and 24, and the like.

The age information of the circuit breaker 2 is, for example, a service life obtained by measuring, for each circuit breaker 2, an accumulated time in a state where the circuit breaker 2 has not performed a cutting operation.

As described above, the collecting unit 712 collects the monitoring information on the use state of the monitoring target including the plurality of circuit breakers 2, and therefore has the following advantages: the use states of the plurality of circuit breakers 2 can be grasped based on the monitoring information collected by the collection unit 712, and usability is improved. For example, when any one of the circuit breakers 2 performs the cutting operation, the collection unit 712 collects monitoring information for a monitoring target including a plurality of circuit breakers 2, and therefore, by integrating the monitoring information collected by the collection unit 712, it is easy to grasp the cause of the cutting operation performed by the circuit breaker 2.

The distribution board 1 of the present embodiment includes a monitoring system 100 and a distribution board cabinet 10 (see fig. 2) that houses the collection unit 712.

In the distribution board 1 of the present embodiment, the collection unit 712 is housed in the distribution board cabinet 10, and the use states of the plurality of circuit breakers 2 can be grasped based on the monitoring information collected by the collection unit 712, so that there is an advantage that the distribution board 1 with improved usability can be provided.

As shown in fig. 1, the monitoring system 100 of the present embodiment includes an output unit 713. The output unit 713 outputs notification information on the use state of the monitoring target including the plurality of circuit breakers 2 housed in the distribution board 1 to the notification unit 73.

In the present embodiment, the output unit 713 outputs notification information on the use state of the monitoring target including the circuit breaker 2 to the notification unit 73. The notification unit 73 is provided in the switchboard 1. Here, the monitoring target of the monitoring system 100 includes at least a plurality of circuit breakers 2 housed in the distribution board 1. The monitoring target may include loads such as a socket (power outlet) 22 (see fig. 1) electrically connected to the circuit breaker 2, and electrical devices 23 and 24 (see fig. 1).

Here, the notification information includes monitoring information obtained by collecting information on the use state of the monitoring target, and information indicating a result obtained by estimating the cause of the circuit breaker 2 performing the breaking operation based on the monitoring information. As described above, the monitoring information on the use state of the monitoring target includes, for example, at least one of the cutting information on the cutting operation of the circuit breaker 2 having the cutting function, the aged information on the degree of deterioration of the circuit breaker 2, and the information on the load electrically connected to the circuit breaker 2.

The collection of the monitoring information by the collection unit 712 of the present embodiment may further include a process of collecting the collected cutting information (state information and cutting cause information) to estimate the cause of the cutting operation, and the monitoring information collected (collected) by the collection unit 712 may further include a result of estimating the cause of the cutting operation.

As described above, the output unit 713 outputs the monitoring information on the use state of the monitoring target including the plurality of circuit breakers 2 to the notification unit 73. Therefore, the user of the switchboard 1 can grasp the use states of the plurality of circuit breakers 2 based on the monitoring information notified by the notification unit 73, and usability is improved. For example, when any of the circuit breakers 2 performs the cutting operation, it is easy to grasp the cause of the cutting operation performed by the circuit breaker 2 based on the monitoring information notified by the notification unit 73.

The distribution board 1 of the present embodiment includes a monitoring system 100 and a distribution board cabinet 10 (see fig. 2) that houses the output unit 713.

In the distribution board 1 of the present embodiment, the output portion 713 is housed in the distribution board cabinet 10. Therefore, the user of the distribution board 1 can grasp the use states of the plurality of circuit breakers 2 based on the monitoring information output to the notification unit 73 by the output unit 713, and thus the distribution board 1 with improved usability can be provided.

(2) Detailed description of the invention

Next, a monitoring system 100 according to the present embodiment and a distribution board 1 including the monitoring system 100 will be described with reference to fig. 1 to 5.

The distribution board cabinet 10 of the distribution board 1 is installed in a facility 500 such as a resident of an independent house or a collective house, for example, and used. The facility 500 in which the switchboard 1 is installed is not limited to individual residents of individual houses or collective houses, and may be installed in non-residential buildings (e.g., factories, commercial buildings, office buildings, hospitals, schools, etc.).

In the following description, unless otherwise specified, the X-axis direction is defined as the left-right direction and the Z-axis direction is defined as the up-down direction in fig. 2 to 4. In addition, a direction orthogonal to each of the X-axis direction and the Z-axis direction is defined as a front-rear direction. The positive direction in the X-axis direction is defined as the right side, and the positive direction in the Z-axis direction is defined as the upper side. However, these directions are examples, and are not intended to limit the directions in which the distribution board cabinet 10 and the distribution board 1 are used. In the drawings, arrows indicating respective directions are merely provided for explanation and do not include entities.

(2.1) Structure

As described above, the distribution board 1 includes the distribution board cabinet 10 that accommodates the circuit breaker 2 and the like.

As shown in fig. 2, the distribution board cabinet 10 accommodates a plurality of circuit breakers 2, a measurement adapter 7, a current measurement device 8, a backup power supply 9 (see fig. 1), and the like. Here, the plurality of circuit breakers 2 includes a main breaker 3, a plurality of branch breakers 4, a shock-sensitive breaker 5, and a tie breaker 6. The distribution board cabinet 10 may house at least the collection portion 712 and the plurality of circuit breakers 2 (see fig. 1). Alternatively, the distribution board cabinet 10 may house at least the circuit breaker 2 and the output portion 713 (see fig. 1). The switchboard cabinet 10 is not necessarily required to house the current measuring device 8 and the backup power supply 9, and can be omitted as appropriate.

The cabinet 10 for the distribution board includes a box-shaped main body 11 (see fig. 2) having an open front surface, and a cover 12 (see fig. 3) that closes the opening of the main body 11. The illustration of the cover 12 is omitted in fig. 2. The distribution board cabinet 10 is mounted to a building member (e.g., a wall 110 of a building). The cabinet 10 for the distribution board may be mounted in a state where a part or the whole of the cabinet is fitted into a mounting hole provided in the wall 110. The cabinet 10 for the distribution board is installed at a height position where a child of average height can not reach the cabinet and a height position where an adult of average height can operate the cabinet.

The distribution board cabinet 10 further includes a cover 13 (see fig. 4), and the cover 13 covers the front surface 121 of the cover 12 in a state where the distribution board cabinet 10 is mounted on the wall 110. The lid 13 is attached to the cover 12 so as to be movable between a closed position and an open position. The closed position is a position covering the front surface 121 of the cover 12 (the position shown in fig. 4), and the open position is a position not covering at least a part of the front surface 121 of the cover 12 (the position shown by the two-dot chain line in fig. 3). The cover 13 may cover a part of the front surface 121 of the cover 12 when the cover 12 is viewed from a certain direction. In the present embodiment, when the cover 12 is viewed from the front of the cover 12, the cover 13 in the closed position covers substantially the entire front surface 121 of the cover 12.

As shown in fig. 2, a main breaker 3, a plurality of branch breakers 4, a vibration-sensitive breaker 5, a communication breaker 6, a measurement adapter 7, and a current measuring device 8 are housed in a distribution board cabinet 10. The main breaker 3, the plurality of branch breakers 4, the shock-sensitive breaker 5, the interconnection breaker 6, the measurement adapter 7, and the current measuring device 8 are mounted to the main body 11 directly or via a mounting member or the like. Fig. 2 shows the arrangement of the main breaker 3, the plurality of branch breakers 4, the shock-sensitive breaker 5, the interconnection breaker 6, the measurement adapter 7, and the current measurement device 8 in the inside of the distribution board cabinet 10, but the arrangement thereof is an example and can be changed as appropriate. In fig. 2, the standby power supply 9 is not shown, but the standby power supply 9 may be disposed at an appropriate position inside the distribution board cabinet 10.

The main breaker 3 is disposed inside the distribution board cabinet 10 and slightly on the left side of the center in the left-right direction. The position of the main breaker 3 in the distribution board cabinet 10 may be other positions such as a position on the right side of the center. The main breaker 3 includes a contact 31 (see fig. 1) electrically connected between the primary-side terminal and the secondary-side terminal. The main breaker 3 includes an operating lever on a front surface thereof for turning on and off the contact 31. The main breaker 3 further includes a detection unit 32 (see fig. 1), and the detection unit 32 detects an abnormal state in which a leakage current flows, for example, at the contact 31. When the detection unit 32 detects an abnormal state in which a leakage current flows through the contact 31, the main breaker 3 opens the contact 31, and cuts off the power supply to the secondary side circuit of the main breaker 3, thereby protecting the circuit. The detection unit 32 may have a function of detecting an overcurrent such as a short-circuit current or an overload current, or the main breaker 3 may open the contact 31 when the detection unit 32 detects the overcurrent. The detection unit 32 may have a function of detecting a neutral-out-of-phase state in the single-phase three-wire wiring, or the main breaker 3 may open the contact 31 when the detection unit 32 detects the neutral-out-of-phase state. The main breaker 3 may have a limiter function of opening the contact 31 when a current exceeding a predetermined limit value flows.

The secondary-side terminal of the main breaker 3 is connected to the conductive rod of the first voltage pole (L1 phase), the conductive rod of the second voltage pole (L2 phase), and the conductive rod of the neutral pole (N phase) in the single-phase three-wire wiring. Each of the conductive bars is formed into a long plate shape elongated in the left-right direction by a conductive member, and is disposed at the center in the vertical direction in the inside of the distribution board cabinet 10 and at the right side of the main breaker 3.

The plurality of branch breakers 4 are disposed so as to be separated from each other on the upper and lower sides of each conductive rod and arranged in a plurality on each side in the left-right direction. In the present embodiment, as shown in fig. 2, 12 branch breakers 4 are arranged above the conductive bars so as to be aligned in the left-right direction. Further, 11 branch breakers 4 are arranged below the conductive bars in the left-right direction.

Each branch breaker 4 includes a pair of primary side terminals and a pair of secondary side terminals. Each branch breaker 4 has a contact electrically connected between the primary-side terminal and the secondary-side terminal. An operation lever for turning on or off a contact built in each branch breaker 4 is provided on the front surface of each branch breaker 4.

The branch breakers 4 include a branch breaker 4 for 100V and a branch breaker 4 for 200V. The 100V branch breaker 4 includes a pair of primary side terminals electrically connected to one of the conductive rod of the first voltage pole and the conductive rod of the second voltage pole and the conductive rod of the neutral pole, respectively. The pair of primary side terminals of the 200V branch breaker 4 are electrically connected to the conductive rod of the first voltage pole and the conductive rod of the second voltage pole, respectively. In addition, a corresponding wiring is electrically connected to the secondary side terminal of the branch breaker 4. The wiring connected to the secondary-side terminal of each branch breaker 4 is connected to, for example, one or more wiring devices such as a lighting device, an electric device 23 such as a hot water supply device, a socket 22 (see fig. 1), and a wall switch as a load. Therefore, the distribution board 1 can supply power to the electric device 23 connected to the secondary-side terminal of the branch breaker 4 via the wiring, the electric device 24 connected to the outlet 22 (for example, an air conditioner, a television receiver, or the like), or the like.

The branch breaker 4 further includes a detection unit 41 (see fig. 1), and the detection unit 41 detects an abnormal state in which an overcurrent such as a short-circuit current or an overload current flows through a contact point included in the branch breaker 4. When the detection unit 41 detects an abnormal state in which an overcurrent flows through the contact, the branch breaker 4 opens the contact to protect the circuit connected to the branch breaker 4. The detection unit 41 may have a function of detecting an abnormal state in which an electric wire or the like starts to be disconnected in a circuit connected to the branch breaker 4. For example, the branch breaker 4 may break the electric circuit when the detection unit 41 detects an arc intermittently generated when the electric wire starts to be broken based on a current waveform of a current flowing through the electric circuit. The detection unit 41 may have a function of detecting a leakage state of the circuit to which the branch breaker 4 is connected, or the branch breaker 4 may interrupt the circuit when the detection unit 41 detects the occurrence of the leakage.

The vibration-sensitive breaker 5 is disposed below the conductive rod so as to be parallel to the branch breaker 4 in the left-right direction. The vibration-sensitive breaker 5 includes a vibration-sensitive sensor 51 for detecting vibration applied to the distribution board cabinet 10. When the vibration sensor 51 detects vibration having a magnitude exceeding a predetermined reference value (for example, seismic motion having an intensity of 5), the vibration-sensitive breaker 5 performs a breaking operation of breaking the circuit. The earthquake-sensitive circuit breaker 5 causes a pseudo electrical leakage state by, for example, electrically connecting the first voltage pole or the second voltage pole and the neutral pole via an impedance element having a relatively low resistance. When the earthquake-sensitive circuit breaker 5 causes the pseudo-leakage state, the detection portion 32 of the main circuit breaker 3 detects the pseudo-leakage state caused by the earthquake-sensitive circuit breaker 5, and the main circuit breaker 3 opens the contact 31. Accordingly, when vibration having a magnitude exceeding the reference value is applied to the switchboard cabinet 10 due to an earthquake or the like, the supply of electric power to the circuit connected to the secondary side of the main breaker 3 can be cut off.

The interconnection breaker 6 is connected to a distributed power supply 21 provided in the facility 500. The tie breaker 6 is electrically connected between the conductive rod electrically connected to the secondary side terminal of the main breaker 3 and the distributed power source 21. When the contacts of the tie breaker are closed, the distributed power source 21 can be interconnected with the system power source 20 to supply power to the load. On the other hand, when the contact of the tie breaker 6 is opened, the distributed power source 21 is disconnected from the system power source 20. The interconnection breaker 6 has a detection function of detecting occurrence of an electric leakage, for example. When the detection function of the interconnection breaker 6 detects the occurrence of the electric leakage, the interconnection breaker 6 performs a breaking operation to disconnect the distributed power supply 21 from the system power supply 20. Further, the interconnection breaker 6 may have a detection function of detecting an overcurrent such as a short-circuit current, and the interconnection breaker 6 may be configured to perform a breaking operation when the overcurrent is detected by the detection function of the interconnection breaker 6.

Here, as shown in fig. 2, a through hole 111 penetrating the bottom wall in the front-rear direction is provided in the bottom wall of the main body 11 accommodating the circuit breaker 2. Therefore, the electric wires introduced from the outside of the distribution board cabinet 10 into the distribution board cabinet 10 through the through-holes 111 are electrically connected to the circuit breakers 2 (the main breaker 3, the branch breakers 4, and the interconnection breaker 6).

The current measuring device 8 is configured to measure a current flowing to a load (

electrical devices

23, 24, etc.) connected to each of the plurality of branch breakers 4. The current measuring device 8 has, for example, a substrate and a plurality of coils. The substrate is in the form of a plate that is long in the left-right direction. A plurality of holes are formed on the substrate. Terminals extending from the conductive bars and connected to the primary-side terminals of the branch breakers 4 are inserted into the plurality of holes, respectively. The coil is, for example, a rogowski coil, formed around the hole of the substrate. In the present embodiment, the current measuring device 8 measures the current flowing to each of the plurality of branch breakers 4 and the tie breaker 6. Here, the current measuring device 8 (current sensor) is shared as a sensor used in an energy management system for managing energy used in the facility 500 in which the distribution board 1 is installed. The current measuring device 8 is not limited to having the rogowski coil, and may have a magnetoresistive element such as a current transformer (current transformer), a hall element, or a GMR (Giant Magnetic Resistances) element, or a sensor such as a shunt resistor.

The backup power supply 9 includes a battery 91 and a charging circuit that charges the battery 91, and the battery 91 is a secondary battery such as a nickel-metal hydride battery or a lithium ion battery. The charging circuit of the backup power supply 9 receives the supply of electric power from the primary side of the main breaker 3 to charge the battery 91. When the system power supply 20 fails, the backup power supply 9 supplies power to the measurement adapter 7 and the like using the battery 91 as a power supply. Therefore, even when the system power supply 20 fails, the measurement adapter 7 can operate by receiving the supply of electric power from the backup power supply 9. That is, the collection unit 712 of the measurement adapter 7 can obtain the operating power from the battery 91 housed in the distribution board 1.

The measurement adapter 7 is disposed inside the distribution board cabinet 10 at a position on the left side of the main breaker 3. The measurement adapter 7 has a measurement function of measuring power passing through at least one of the main breaker 3 and the branch breaker 4 in the distribution board 1, and a communication function of communicating with a device disposed outside the distribution board cabinet 10. In the present embodiment, the measurement adapter 7 has a function of collecting monitoring information on the use state of the monitoring target including the circuit breaker 2. Since the measurement adapter 7 operates by receiving power supply from the primary side of the main breaker 3, the measurement adapter 7 can operate even when the main breaker 3 performs a breaking operation. Further, since the measurement adapter 7 receives power supply from the backup power supply 9 when the system power supply 20 fails, the measurement adapter 7 can operate even when the system power supply 20 fails.

More specifically, the measurement adapter 7 of the present embodiment includes a control unit 71, a communication unit 72, a notification unit 73, and a storage unit 74. In the present embodiment, the monitoring system 100 is configured by the measurement adapter 7 including the collection unit 712.

The measurement adapter 7 comprises, for example, a computer system. The computer system has a main structure of a processor and a memory as hardware. The function as the control section 71 is realized by a processor executing a program recorded in a memory of a computer system. The program may be recorded in advance in a memory of the computer system, may be provided through an electric communication line, or may be provided by recording in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive readable by the computer system.

The control unit 71 has at least the functions of the measurement unit 711, the collection unit 712, and the output unit 713.

The measurement adapter 7 of the present embodiment is electrically connected to a main current measurement device for measuring a current flowing through the main breaker 3 and a current measurement device 8. Here, the main current measuring device includes a current sensor including, for example, a Current Transformer (CT). The measurement unit 711 of the measurement adapter 7 measures power passing through at least one of the main breaker 3 and the branch breaker 4 in the distribution board 1. Specifically, the measurement unit 711 receives, from the current measurement device 8, the current value flowing to each of the plurality of branch breakers 4 and the tie breaker 6 measured by the current measurement device 8. The measurement unit 711 of the measurement adapter 7 receives the current value measured by the main current measurement device from the main current measurement device. The measurement unit 711 converts the current values measured by the current measurement device 8 and the main current measurement device into power values (instantaneous power values), respectively. The measurement unit 711 also has a function of calculating data of the amount of electric power obtained by integrating the collected data of the instantaneous power for a predetermined time.

The collection unit 712 collects monitoring information on the usage state of the monitoring target including the plurality of circuit breakers 2 housed in the distribution board 1. The collection unit 712 periodically collects monitoring information. For example, the collecting unit 712 collects, as the monitoring information, the current values of the currents flowing through the respective circuit breakers 2 from the main current measuring device and the current measuring device 8. The collecting unit 712 collects the measurement result of the vibration sensor 51 from the vibration-sensitive breaker 5 as monitoring information. For example, when the measurement adapter 7 and the vibration-sensitive circuit breaker 5 each have a wireless communication function, the measurement adapter 7 communicates with the vibration-sensitive circuit breaker 5, and the collection unit 712 collects the measurement result of the vibration-sensitive sensor 51 from the vibration-sensitive circuit breaker 5. The measurement adapter 7 may be configured to acquire a measurement result from a voltage measurement unit that measures an inter-terminal voltage of the secondary-side terminal of the circuit breaker 2, and the collection unit 712 may be configured to collect information indicating whether or not each circuit breaker 2 performs a cutting operation based on the measurement result of the voltage measurement unit.

When any of the circuit breakers 2 performs the cutting operation, the control unit 71 collects the monitoring information collected by the collection unit 712 to estimate which of the causes of the cutting operation of the circuit breaker 2 is a leakage, a short circuit, an overload, an earthquake, a lightning strike, and the like.

The output unit 713 stores, in the storage unit (data storage unit) 74, notification information including the monitoring information collected by the collection unit 712 and information of a result obtained by the control unit 71 estimating the cause of the cutting operation by aggregating the monitoring information. Here, the output unit 713 may store the notification information (the monitoring information and the estimation result of the cause of the cutting operation) in the storage unit 74 before the circuit breaker 2 cuts the circuit, or may store the notification information in the storage unit 74 after the circuit breaker 2 cuts the circuit. Here, the storage unit 74 stores the notification information (the monitoring information and the estimation result of the cause of the shutdown operation) in the ring buffer. Although the storage unit 74 overwrites the oldest monitoring information with the latest monitoring information, the output unit 713 may store the notification information in the storage unit 74 so as not to overwrite the monitoring information for a predetermined period before the cutting operation is performed. In addition, when any of the circuit breakers 2 performs the cutting operation, the output unit 713 may store the notification information in the storage unit 74 so as not to cover the monitoring information of the circuit breaker 2 that has performed the cutting operation. That is, the collecting unit 712 stores at least monitoring information on the circuit breaker 2 that has performed the cutting operation among the plurality of circuit breakers 2.

At the time of notifying the user of the distribution board 1 of the notification information (the monitoring information and the estimation result of the cause of the disconnection operation), the output unit 713 outputs the notification information read out from the storage unit 74 to the notification unit 73, and the notification unit 73 performs a notification operation for notifying the notification information. Here, the timing at which the notification unit 73 notifies the notification information is, for example, a predetermined period of time after any one of the circuit breakers 2 performs the cutting operation. Note that the notification of the notification information may be performed at a timing when the user of the distribution board 1 turns on again the circuit breaker 2 that has performed the cutting operation after any one of the circuit breakers 2 has performed the cutting operation. The output unit 713 may notify the notification information at a timing when, for example, a human detection sensor disposed in the distribution board cabinet 10 detects a person in the vicinity of the distribution board cabinet 10 after any one of the circuit breakers 2 performs the breaking operation. The human body sensor is, for example, an infrared detection type sensor that detects infrared rays radiated from a human body, but may be a sensor that detects the presence of a human body using ultrasonic waves, radio waves, or the like, or may be a sensor that detects the presence of a human body from an image of an image sensor. The output unit 713 may notify the notification information after any of the circuit breakers 2 has performed the cutting operation, for example, at a timing when a sensor for detecting opening and closing of the lid 13 detects that the lid 13 is opened.

In this way, since the notification unit 73 notifies the notification information, the user of the switchboard 1 can confirm the notification information (the monitoring information and the estimation result of the cause of the disconnection operation) notified from the notification unit 73. Therefore, the user of the distribution board 1 can grasp the cause of the cutting operation based on the notification information notified from the notification unit 73 before performing the operation of returning the circuit breaker 2 that has performed the cutting operation. Therefore, the user of the distribution board 1 can perform a recovery operation of recovering the circuit breaker 2 that has performed the cutting operation, after grasping the cause of the cutting operation.

Further, even when the main breaker 3 performs the interrupting operation, since the electric power is supplied from the primary side of the main breaker 3 to the measurement adapter 7, the collecting unit 712 can perform the collecting operation of collecting the monitoring information and the notification unit 73 can perform the notification operation of notifying the notification information. Further, since power is supplied from the backup power supply 9 to the measurement adapter 7 when the system power supply 20 fails, the collection unit 712 can perform a collection operation of collecting monitoring information, and the notification unit 73 can perform a notification operation of notifying notification information. In the present embodiment, the backup power supply 9 is provided outside the measurement adapter 7, but the backup power supply 9 may be incorporated in the measurement adapter 7.

The communication unit 72 communicates with the controller 25 and the like provided in the facility 500. The controller 25 controls or monitors a device (hereinafter referred to as an HEMS-supporting device) that supports HEMS (Home Energy Management System). That is, the controller 25 can acquire instantaneous power and the amount of power of each of a plurality of loads (

electric devices

23, 24, and the like) connected to a plurality of branch breakers 4 by communicating with the measurement adapter 7, and can control or monitor the HEMS support device. The controller 25 is disposed outside the distribution board cabinet 10. Here, the HEMS supporting apparatus includes, for example, a Smart meter (Smart meter), a solar power generation device, an electric storage device, a fuel cell, an electric vehicle, an air conditioner, a lighting fixture, a hot water supply device, a refrigerator, a television receiver, or the like. In addition, the HEMS support apparatus is not limited to these apparatuses.

The communication method between the communication unit 72 and the controller 25 is radio communication via radio waves in accordance with a communication standard such as a specific low-power radio base station (a radio base station not requiring a license) in a 920MHz band, Wi-Fi (registered trademark), or Bluetooth (registered trademark), for example. The communication method between the communication unit 72 and the controller 25 may be wired communication conforming to a communication standard such as a wired LAN (Local Area Network). The communication protocol for communication between the communication unit 72 and the controller 25 is, for example, Ethernet (registered trademark), ECHONET Lite (registered trademark), or the like.

The communication unit 72 has a communication function of communicating with the management server 300 and the mobile terminal 400 via the wide area network 200 such as the internet. Here, the portable terminal 400 is a terminal carried by a user of the distribution board 1, and is, for example, a smartphone or a tablet computer.

The notification unit 73 includes a light-emitting display unit 731 provided in the measurement adapter 7 and a speaker. The notification unit 73 uses the light-emitting display unit 731 (see fig. 2) and the speaker to perform notification based on the notification information (the monitoring information and the estimation result of the cause of the shut-off operation) stored in the storage unit 74. The light-emission display unit 731 includes, for example, a plurality of light-emitting diodes whose emission colors are color-classified according to the cause of the cutoff operation. The light-emitting display portion 731 is provided on the surface of the measurement adapter 7 at a position exposed from the opening of the front surface 121 of the cover 12. The notification unit 73 causes, for example, a light-emitting diode of a light emission color corresponding to the cause of the cutoff operation to emit light based on the notification information output from the output unit 713. The notification unit 73 outputs a voice message notifying the cause of the cutting operation by voice from the speaker based on the notification information output from the output unit 713. As described above, in the present embodiment, the notification unit 73 notifies the notification information by both light and sound, but the notification unit 73 may notify the notification information (monitoring information) by at least one of light and sound.

The storage unit 74 includes, for example, a non-volatile Memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) that can be Electrically rewritten, and a volatile Memory such as a RAM (Random Access Memory). The storage unit 74 stores information such as the monitoring information collected by the collection unit 712. In the present embodiment, the data storage unit is a storage unit 74 provided in the switchboard 1.

(2.2) operation

The operation of the monitoring system 100 according to the present embodiment will be described with reference to fig. 5.

The collection unit 712 of the monitoring system 100 (measurement adapter 7) periodically performs a collection process of collecting monitoring information for a monitoring target including the plurality of circuit breakers 2 (S1), and stores the collected monitoring information in the storage unit 74.

The control unit 71 of the measurement adapter 7 determines whether or not an abnormality such as a cutting operation of the circuit breaker 2 has occurred based on the monitoring information collected by the collection unit 712 (S2).

If an abnormality has not occurred (no in S2), the collection unit 712 of the measurement adapter 7 periodically performs a collection process of collecting monitoring information for a monitoring target including a plurality of circuit breakers 2 (S1), and stores the collected monitoring information in the storage unit 74.

On the other hand, when an abnormal event occurs (yes in S2), in the monitoring system 100, the collection unit 712 collects monitoring information (S3) before any circuit breaker 2 performs the breaking operation, and stores the collected monitoring information in the storage unit 74. Further, the control unit 71 estimates the cause of the cutting operation based on the monitoring information collected by the collection unit 712, and stores the estimation result of the cause of the cutting operation in the storage unit 74. In this way, when the circuit breaker 2 performs the cutting operation, the collection unit 712 collects the monitoring information and the output unit 713 stores the notification information including the monitoring information and the estimation result of the cause of the cutting operation in the storage unit 74, so that the notification information of the timing at which the cutting operation is performed can be stored. Therefore, the user of the distribution board 1 can grasp the cause of the cutting operation based on the notification information stored in the storage unit 74 after the circuit breaker 2 performs the cutting operation. Further, since the monitoring information also includes information on the use states of the outlet 22 and the

electrical devices

23 and 24, the user of the distribution board 1 can easily grasp the use states of the outlet 22 and the

electrical devices

23 and 24 based on the monitoring information. Further, since the monitoring information also includes the chronological information of the outlet 22 and the

electrical devices

23 and 24, the user of the distribution board 1 can easily grasp the degree of deterioration, the replacement timing, and the like of the outlet 22 and the

electrical devices

23 and 24 based on the monitoring information.

Thereafter, when any of the circuit breakers 2 performs the breaking operation (S4), since the electrical equipment connected to the broken circuit or the like stops operating, the user of the distribution board 1 (the resident of the facility 500 or the like) moves to the place where the distribution board 1 is installed, and confirms the state of the distribution board 1.

Here, when the human detection sensor provided in the switchboard 1 detects a person approaching the switchboard 1 (S5: yes), the output unit 713 performs an operation of outputting the notification information based on the notification information stored in the storage unit 74. That is, the output unit 713 outputs the notification information stored in the storage unit 74 to the notification unit 73, and the notification unit 73 performs notification based on the notification information (S6). The notification unit 73 performs notification processing by, for example, lighting a light emitting diode of a light emission color corresponding to the cause of the shut-off operation based on the notification information, or outputting a voice message for notifying the cause of the shut-off operation from a speaker.

Thus, a user in the vicinity of the distribution board 1 can recognize the cause of the circuit breaker 2 performing the breaking operation by hearing the voice message output from the speaker or opening the cover 13 to see the display of the light emitting diode. Therefore, the user can grasp what the cause of the cutting operation of the circuit breaker 2 is before the recovery operation of recovering the circuit breaker 2 is performed, and can take appropriate measures to eliminate the cause of the cutting operation of the circuit breaker 2. For example, if the cause of the cutting operation of the circuit breaker 2 is an overcurrent, the user can eliminate the cause of the cutting operation by stopping the electrical equipment connected to the circuit breaker 2 that has performed the cutting operation. Further, if the cause of the cutting operation of the circuit breaker 2 is an electric leakage, a short circuit, a neutral line phase loss, or the like, the user takes a response such as requesting an electrical engineering service provider or the like to perform an inspection, and thereby the electrical equipment can be safely used. In this way, the user of the distribution board 1 can perform the restoration operation of restoring the circuit breaker 2 after performing the processing for eliminating the cause of the breaking operation, and thus can appropriately perform the operation of restoring the circuit breaker 2.

(3) Modification example

The above-described embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be variously modified according to design and the like as long as the object of the cost disclosure can be achieved. The same functions as those of the monitoring system 100 can be realized by a monitoring method, a computer program, a non-transitory recording medium in which a program is recorded, or the like.

In the monitoring method according to one embodiment, monitoring information on the use state of a monitoring object including a plurality of circuit breakers 2 housed in a distribution board 1 is collected. A (computer) program according to one embodiment is a program for causing a computer system to execute the monitoring method described above.

In the monitoring method according to one embodiment, notification information (including monitoring information and a result of estimation of a cause of the disconnection operation) about a usage state of a monitoring target including the plurality of circuit breakers 2 housed in the distribution board 1 is output to the notification unit 73. A (computer) program according to one embodiment is a program for causing a computer system to execute the monitoring method described above.

Next, modifications of the above embodiment will be described. The modifications described below can be applied in appropriate combinations. In addition, the above-described embodiment may be referred to as a "basic example" hereinafter.

The monitoring system 100 in the present disclosure includes a computer system in the collection unit 712 and the like, for example. The computer system has a main structure of a processor and a memory as hardware. The functions as the monitoring system 100 in the present disclosure are realized by executing a program recorded in a memory of a computer system by a processor. The program may be recorded in advance in a memory of the computer system, may be provided through an electric communication line, or may be recorded in a non-transitory recording medium such as a memory card, an optical disc, or a hard disk drive readable by the computer system. A processor of a computer system is constituted by one or more electronic circuits including a semiconductor Integrated Circuit (IC) or a large scale integrated circuit (LSI). The term "integrated circuit" as used herein, such as an IC or an LSI, is referred to variously depending on the degree of Integration, and includes integrated circuits called a system LSI, a VLSI (Very Large Scale Integration) or an ULSI (Ultra Large Scale Integration). Furthermore, an FPGA (Field-Programmable Gate Array) that is programmed after LSI manufacturing or a logic device that can reconstruct the connection relationship inside LSI or the circuit division inside LSI can also be used as a processor. The plurality of electronic circuits may be integrated on one chip or may be dispersed over a plurality of chips. The plurality of chips may be integrated in one device or may be distributed among a plurality of devices. A computer system as referred to herein includes a microcontroller having more than one processor and more than one memory. Thus, the microcontroller is also constituted by one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Note that the integration of a plurality of functions in the monitoring system 100 into one housing (measurement adapter 7) is not an essential configuration for the monitoring system 100, and the components of the monitoring system 100 may be provided in a plurality of housings in a distributed manner. The functions of at least a part of the monitoring system 100, such as the collection unit 712, may be implemented by, for example, a cloud (cloud computing). Conversely, as in the above-described embodiment, all the functions of the monitoring system 100 may be integrated into one housing (measurement adapter 7).

In the above embodiment, the "excess" may be "or more" in comparison between two values such as the measured value of the current. That is, in the comparison between two values, whether or not the two values are equal to each other can be arbitrarily changed depending on the setting such as the reference value, and there is no technical difference between "exceeding" and "exceeding".

(3.1) modification 1

In the basic example, the notification unit 73 notifies the notification information using the light-emitting display unit 731 or the speaker provided in the switchboard 1, but the notification information may be notified using a display device provided in the switchboard 1, for example.

The display device is a thin display device such as a liquid crystal display or an organic EL (Electro Luminescence) display, and is attached to the front surface of the lid 13 or the front surface 121 of the cover 12 (see fig. 3 and 4).

In this case, the output unit 713 outputs the notification information read from the storage unit 74 to the notification unit 73 at the timing when the notification information is notified to the user of the switchboard 1, and the notification unit 73 displays the notification information on the display device. Here, since the distribution board 1 is provided with the backup power supply 9, even when the system power supply 20 is in a power failure state, the notification unit 73 and the display device can receive power supply from the backup power supply 9 and display notification information on the display device.

In the present modification, the notification unit 73 may simultaneously perform both a process of displaying the notification information on the display device and a process of outputting the voice message including the notification information on the speaker, and may perform notification of the notification information by both the display and the voice.

(3.2) modification 2

In the basic example, the output unit 713 of the monitoring system 100 stores the notification information including the monitoring information collected by the collection unit 712 and the estimation result of the cause of the disconnection operation in the storage unit 74 of the distribution board 1 (the measurement adapter 7 in the basic example), but the storage location of the notification information may be outside the distribution board 1.

For example, the output unit 713 may transmit notification information (monitoring information and a result of estimation of the cause of the disconnection operation) to the management server 300 via the communication unit 72 and store the notification information in a storage unit included in the management server 300. That is, in modification 2, the data storage unit is the management server (computer system) 300 that receives notification information from the output unit 713 via the wide area network (network) 200.

Since the management server 300 is located outside the facility 500, even when the area including the facility 500 has a power failure, the management server 300 is less likely to be affected by the power failure, and can store the notification information.

When the notification information is stored in the management server 300, the user of the distribution board 1 accesses the management server 300 using the mobile terminal 400 or the computer terminal to browse the notification information stored in the management server 300. That is, when the management server 300 serving as the notification unit is accessed from the mobile terminal 400 or the computer terminal, the notification information stored in the storage unit is output to the mobile terminal 400 or the computer terminal. In modification 2, the notification unit is a management server (computer system) 300 connected to the output unit 713 (measurement adapter 7) via the wide area network (network) 200. Thus, the user of the distribution board 1 can browse the notification information stored in the management server 300 by using the mobile terminal 400 or the computer terminal. Therefore, the user of the distribution board 1 can grasp the cause of the cutting operation based on the monitoring information collected by the collection unit 712 and the estimation result of the cause of the cutting operation.

The output unit 713 of the monitoring system 100 may transmit the notification information to the mobile terminal 400 via the communication unit 72, and store the notification information in a storage unit included in the mobile terminal 400. That is, the data storage unit is a portable computer system that receives notification information from the output unit 713 via the wide area network (network) 200. In this case, application software for acquiring notification information from the monitoring system 100 and notifying a user is installed in the portable terminal 400. By executing the application software by the processor of the portable terminal 400, a function of acquiring notification information from the monitoring system 100 and notifying the acquired notification information is realized.

Since the mobile terminal 400 operates by receiving electric power from a built-in battery, even when power is lost in an area including the facility 500, the mobile terminal 400 is less likely to be affected by the power loss, and can store notification information.

When the notification information is stored in the portable terminal 400, the user of the distribution board 1 uses the portable terminal 400 to browse the notification information stored in the storage unit of the portable terminal 400. That is, when the mobile terminal 400 serving as the notification unit receives an operation by the user, the notification information stored in the storage unit is displayed on the display device of the mobile terminal 400, or the notification information is output from the speaker of the mobile terminal 400 by a voice message or the like. Thus, the user of the distribution board 1 can browse the notification information using the mobile terminal 400 serving as the notification unit, and can grasp the cause of the cutting operation based on the monitoring information collected by the collection unit 712 and the estimation result of the cause of the cutting operation.

(3.3) modification 3

In the basic example, the notification unit 73 notifies the notification information using the light-emitting display unit 731 or the speaker provided in the switchboard 1, but the output unit 713 may transmit an email including the notification information to a mail address as a notification destination. Here, the user of the distribution board 1 or the like registers a mail address as a notification destination in the monitoring system 100 in advance. The mail address as the notification destination is, for example, a mail address of the mobile terminal 400 carried by the user of the power distribution board 1.

The collection unit 712 periodically collects monitoring information, and the output unit 713 stores the monitoring information collected by the collection unit 712 in the storage unit 74. When any of the circuit breakers 2 performs the cutting operation, the output unit 713 also stores the estimation result obtained by estimating the cause of the cutting operation based on the monitoring information in the storage unit 74. When any of the circuit breakers 2 performs the cutting operation, the output unit 713 creates an electronic mail including the notification information read out from the storage unit 74, and transmits the created electronic mail from the communication unit 72 to the mail address as the transmission destination. At this time, when the mobile terminal 400 receives the notification of the reception of the email, the user of the switchboard 1 operates the mobile terminal 400 to open the email, thereby being able to view the notification information included in the email. Therefore, the user of the distribution board 1 can browse the notification information using the mobile terminal 400 serving as the notification unit, and can grasp the cause of the cutting operation based on the monitoring information collected by the collection unit 712 and the estimation result of the cause of the cutting operation.

(3.4) other modifications

In the basic example, the collection unit 712 periodically collects the monitoring information, but the time interval at which the collection unit 712 collects the monitoring information may be fixed to a constant time or may be changed to an arbitrary time. That is, the collecting unit 712 can change the time interval for collecting the monitoring information.

For example, when it is determined based on the monitoring information collected by the collection unit 712 that there is a high possibility that any one of the circuit breakers 2 performs the cutting operation, the control unit 71 may set the time interval at which the monitoring information is collected by the collection unit 712 to be shorter than the time interval at which the circuit breaker 2 does not perform the cutting operation in the normal state.

In the basic example, the control unit 71 may estimate the cause of the circuit breaker 2 performing the breaking operation using, for example, a learning completion model obtained by machine learning. Further, the learning completion model used by the control unit 71 may be capable of performing relearning while the monitoring system 100 is in use.

In the basic example, the notification unit 73 notifies the monitoring information collected by the collection unit 712 and the notification information including the result of the control unit 71 estimating the cause of the cutting operation based on the monitoring information, but the notification unit 73 does not necessarily notify the estimation result of the cause of the cutting operation. The notification unit 73 may notify only the monitoring information collected by the collection unit 712, and the user of the switchboard 1 can easily grasp the cause of the cutting operation based on the monitoring information notified by the notification unit 73.

(embodiment mode 2)

(1) Summary of the invention

As shown in fig. 6, the monitoring system 100A of the present embodiment is used for monitoring a circuit connected to the distribution board 1. The monitoring system 100A includes a detection unit 712A and a presentation unit 713A. In the present embodiment, the components of the monitoring system 100A are components included in the measurement adapter 7 disposed inside the distribution board 1.

The detection unit 712A detects the occurrence of an event related to the circuit connected to the distribution board 1. The "circuit connected to the distribution board" according to the present disclosure may include a main breaker 3, a branch breaker 4, a shock-sensitive breaker 5, and a communication breaker 6, which are provided inside the distribution board 1. The "circuit connected to the distribution board" in the present disclosure may further include a receptacle 22 or an electrical device 24 electrically connected to the secondary side of the branch breaker 4, or an electrical device 23 directly electrically connected to the secondary side of the branch breaker 4. Also, the "circuit" referred to in this disclosure can include the distributed power source 21 electrically connected to the secondary side of the tie breaker 6.

The "event" referred to in the present disclosure may include, for example, a time when the circuit breaker 2, such as the main breaker 3 or the branch breaker 4, breaks the circuit or when the circuit breaker 2 is degraded over time and the circuit breaker 2 needs to be replaced with a new circuit breaker. The circuit breaker 2 breaks the circuit when an abnormal current such as a short-circuit current, a leakage current, or an overcurrent flows, when a surge current generated by a lightning strike flows, when a phase loss of a neutral line occurs in a single-phase three-wire wiring, when an earthquake occurs, or the like. In the present embodiment, when the circuit breaker 2 breaks the circuit, the detection unit 712A detects the occurrence of a power failure due to the breaking operation of the circuit breaker 2 as an event.

When the occurrence of an event is detected by the detection section 712A, the presentation section 713A presents recommendation information relating to an action that the user should take in accordance with the event. The "subscriber" referred to in the present disclosure is a subscriber of the distribution board 1, and for example, if the facility 500 in which the distribution board 1 is installed is a house, the "subscriber" referred to in the present disclosure is a resident. That is, the "user" referred to in the present disclosure is basically a user of the facility 500 in which the switchboard 1 is installed.

For example, when the circuit breaker 2 breaks the circuit (that is, a power failure occurs) is an event, the "recommendation information" referred to in the present disclosure includes a procedure to be executed by the user to restore the circuit including the circuit breaker 2. That is, in the present embodiment, the presentation unit 713A presents, as the recommendation information, the recovery information including a step for recovering from the power outage. In addition, for example, when a time when it is necessary to replace the circuit breaker 2 with a new circuit breaker is an event, "recommendation information" referred to in the present disclosure includes information that urges a user to replace the circuit breaker 2 with a new circuit breaker.

As described above, in the present embodiment, when an event related to a circuit connected to the distribution board 1 occurs, the presentation unit 713A presents recommendation information related to an action to be taken by the user in accordance with the event. Therefore, the user can know what action should be taken with respect to the occurred event by confirming the recommendation information. That is, the present embodiment has an advantage that usability of the user can be improved.

(2) Detailed description of the invention

Next, the monitoring system 100A and the switchboard 1 including the monitoring system 100A according to the present embodiment will be described in detail with reference to fig. 6. In the following, the description of the parts common to the monitoring system 100A of embodiment 1 is omitted.

(2.1) switchboard

First, the switchboard 1 will be explained. As shown in fig. 6, the distribution board 1 includes a monitoring system 100A and a distribution board cabinet 10 that houses the monitoring system 100A. The cabinet 10 for distribution board does not necessarily have to accommodate the measurement adapter 7, the current measurement device 8, and the backup power supply 9, and can be omitted as appropriate.

In the present embodiment, when an overcurrent such as a short-circuit current or an overload current is detected by the detection unit 32, the main breaker 3 opens the contact 31. The detection unit 32 of the main breaker 3 has a function of detecting a phase-missing state of the neutral line in the single-phase three-wire wiring. When the detection unit 32 detects a phase loss state of the neutral line, the main breaker 3 opens the contact 31.

In the present embodiment, the detection unit 41 of the branch breaker 4 has a function of detecting a leakage state of the circuit to which the branch breaker 4 is connected. When the detection unit 41 detects the occurrence of the electric leakage, the branch breaker 4 breaks the electric circuit.

(2.2) monitoring System

Next, the monitoring system 100A will be described with reference to fig. 6. In the present embodiment, as described above, since the components of the monitoring system 100A are included in the measurement adapter 7, the following description will be given of the measurement adapter 7 together with the monitoring system 100A. The measurement adapter 7 of the present embodiment includes a control unit 71, a communication unit 72, a remote notification unit 73A, a storage unit 74, and a user detection unit 75.

Unlike embodiment 1, the control unit 71 includes the functions of the detection unit 712A, the presentation unit 713A, and the determination unit 714, instead of the collection unit 712 and the output unit 713.

The detection unit 712A detects the occurrence of an event related to the circuit connected to the distribution board 1. For example, the detection unit 712A collects current values of currents flowing through the plurality of circuit breakers 2 from the measurement unit 711. The detection unit 712A collects the measurement result of the vibration sensor 51 from the vibration-sensitive breaker 5 as monitoring information. For example, when the measurement adapter 7 and the vibration-sensitive circuit breaker 5 each have a wireless communication function, the measurement adapter 7 communicates with the vibration-sensitive circuit breaker 5, and the detection unit 712A collects the measurement result of the vibration-sensitive sensor 51 from the vibration-sensitive circuit breaker 5. Then, the detection unit 712A detects that any of the circuit breakers 2 has performed a breaking operation, that is, the occurrence of a power failure as an event, based on the collected information. When detecting that any of the circuit breakers 2 has performed the breaking operation, the detection unit 712A estimates, based on the collected information, which of the causes of the breaking operation of the circuit breaker 2 is an electric leakage, a short circuit, an overload, a neutral line phase loss, an earthquake, a lightning stroke, and the like.

Further, the detection unit 712A estimates aged information related to aged deterioration of the circuit breaker 2 based on the collected information. The age information of the circuit breaker 2 is, for example, a service life obtained by measuring an accumulated time in a state where the circuit breaker 2 does not perform the cutting operation for each circuit breaker 2.

The estimation result (the cause of the cutting operation of the circuit breaker 2 and the information on the elapsed time of the circuit breaker 2) estimated by the detection unit 712A is stored in the storage unit 74. Here, when the estimation result of the cause of the cutting operation of the circuit breaker 2 is stored in the storage unit 74, the detection unit 712A may be stored in the storage unit 74 before the circuit breaker 2 cuts the circuit, or may be stored in the storage unit 74 after the circuit breaker 2 cuts the circuit.

When the occurrence of an event is detected by the detection section 712A, the presentation section 713A presents recommendation information relating to an action that the user should take in accordance with the event. In the present embodiment, the storage unit 74 stores recommendation information in one-to-one association with events. Then, the presentation unit 713A reads recommendation information corresponding to the occurred event from the storage unit 74 at an appropriate timing after the occurrence of the event, and presents the read recommendation information by an appropriate means.

For example, the presentation unit 713A visually presents recommendation information to the user by displaying a character string and/or an image on a display device (e.g., a liquid crystal display or the like) provided in the measurement adapter 7 or a display device connected to the measurement adapter 7. In addition, for example, the presentation section 713A audibly presents the recommendation information to the user by outputting a voice message from a speaker provided in the measurement adapter 7 or a speaker connected to the measurement adapter 7.

Here, when the occurrence of a power outage due to the cutting operation of the circuit breaker 2 is an event, the presentation unit 713A presents, as the recommendation information, the recovery information including a procedure for recovering from the power outage. Next, a specific example of the restoration information of each cause of the cutting operation of the circuit breaker 2 (that is, the cause of the power failure) will be described.

When a power failure occurs due to an earthquake, the presentation unit 713A presents, as the recovery information, the step of turning on the main breaker 3, or when the earthquake sensitive breaker 5 has the tilt detection function, the presentation unit 713A presents the step of turning on the main breaker 3 together with the step of resetting the tilt detection function. In consideration of the case where the user cannot recover from the power outage, the presentation unit 713A presents, as the recovery information, the contact information of the contact method with the electrical engineering carrier and the information urging the electrical engineering carrier to contact. The "contact means" referred to herein may include, for example, a telephone number, a mail address, or, in the case where a homepage is opened by an electrical engineering carrier, a URL (Uniform Resource Locator) of the homepage.

When a power failure occurs due to a power leakage, the presentation unit 713A presents the following as the recovery information: all the branch breakers 4 are first turned off, then the main breaker 3 is turned on, and then the branch breakers 4 are turned on one by one. When the main breaker 3 is turned off at the time when any one of the branch breakers 4 is turned on, the presentation unit 713A presents, as the restoration information, information indicating that the leakage is generated in the circuit to which the branch breaker 4 is connected. Also, the presentation section 713A presents the following as the resume information: the main breaker 3 is turned on after the branch breakers 4 other than the branch breaker 4 in which the electric leakage is generated are turned on. In addition, in consideration of the case where the user cannot recover from the power outage, the presentation unit 713A presents, as the recovery information, the contact information of the contact with the electrical engineering carrier and the intention of urging the contact with the electrical engineering carrier.

When a power failure occurs due to a short circuit or a phase loss of the neutral line, the presentation unit 713A presents, as the restoration information, a contact method for contacting the electrical engineering carrier and a message urging the electrical engineering carrier to contact.

When power failure occurs due to overload, the presentation unit 713A presents, as the restoration information, information that urges a reduction in the number of used

electric devices

23 and 24. In this case, the presentation unit 713A may present, as the restoration information, a reminder to avoid setting the electric devices 23 and 24 (for example, refrigerators) that would otherwise hinder life if they were not used, to the unused state. In addition, in consideration of the case where the user cannot recover from the power outage, the presentation unit 713A presents, as the recovery information, the contact information of the contact with the electrical engineering carrier and the intention of urging the contact with the electrical engineering carrier.

When the time when it is necessary to replace the circuit breaker 2 with a new circuit breaker is an event, the presentation unit 713A presents information that urges the replacement of the circuit breaker 2 with the new circuit breaker as the recommendation information.

In the present embodiment, when the event is a power outage, the presentation unit 713A presents confirmation information including a procedure for safety confirmation to be performed by the user before presenting the recommendation information. The confirmation information is stored in the storage unit 74 so as to be associated with the event in a one-to-one manner, similarly to the recommendation information. The presentation method of the confirmation information is the same as that of the restoration information (recommendation information). The confirmation information may include, for example, a meaning urging the user to confirm whether the

electric devices

23 and 24 are in the operating state or in the stopped state, a meaning urging the user to confirm whether or not the power plugs of the

electric devices

23 and 24 are removed from the outlet 22, or the like.

In the present embodiment, when the determination unit 714 determines that the user has performed the security check step, the presentation unit 713A presents the restoration information. Here, determination unit 714 determines whether or not the user has performed a security confirmation procedure. For example, the determination unit 714 determines that the user has performed the security confirmation procedure when an operation unit (e.g., a key or the like) disposed in the measurement adapter 7 is operated. That is, the user operates the operation section of the measurement adapter 7 after the step of performing security confirmation in accordance with the confirmation information when the confirmation information is presented by the presentation section 713A. At this time, the presentation unit 713A may notify the user of "security confirmation made? "etc. The presentation unit 713A may notify the user of an operation unit to be operated by the user, for example, which key of the measurement adapter 7 should be pressed, using a display device or a speaker.

In the present embodiment, when the event is the occurrence of a power outage due to the cutting operation of the circuit breaker 2, the presentation unit 713A presents the recovery information when the user performs the recovery operation for recovering from the power outage. The term "when the recovery job is performed" in the present disclosure includes a time point at which the monitoring system 100A directly or indirectly confirms that the user intends to perform the recovery job. For example, the presentation unit 713A presents the restoration information based on the detection result of the user detection unit 75 described later. That is, when the user detection unit 75 detects an operation that becomes a starting point of the recovery job performed by the user, the presentation unit 713A presents the recovery information.

In the present embodiment, even when the main breaker 3 performs the breaking operation, power is supplied from the primary side of the main breaker 3 to the measurement adapter 7. Therefore, when the system power supply 20 is not powered off, the detection unit 712A and the presentation unit 713A can operate. When the system power supply 20 fails, power is supplied from the backup power supply 9 to the measurement adapter 7. Therefore, even when the system power supply 20 fails, the detection unit 712A and the presentation unit 713A can operate.

The remote notification unit 73A has a communication function of communicating with the management server 300 and the information terminal 400A via the wide area network 200 such as the internet. Here, the information terminal 400A is, for example, a terminal carried by a user of the distribution board 1, and is, for example, a smartphone or a tablet computer. The information terminal 400A may be, for example, a desktop or laptop personal computer. The remote notification unit 73A notifies the information terminal 400A of the user of the restoration information and the procedure of security confirmation (that is, the confirmation information) to be performed by the user.

For example, when the circuit breaker 2 performs a breaking operation (power failure occurs), the remote notification unit 73A transmits a signal including the restoration information read from the storage unit 74 and the confirmation information read from the storage unit 74 to the information terminal 400A in accordance with the cause of the power failure. The user can know the restoration information and the confirmation information by operating the information terminal 400A to, for example, browse a mail or start an application program for the monitoring system 100A installed in the information terminal 400A.

The storage unit 74 stores the recommendation information and the confirmation information in addition to the monitoring information and the like collected by the collection unit 712 described in embodiment 1. The storage unit 74 stores the cause of the power failure, which is the cutting operation performed by the circuit breaker 2.

After any one of the circuit breakers 2 performs the cutting operation, the user detection unit 75 detects an operation that becomes a starting point for the user to perform the recovery operation. For example, the user detection unit 75 is an input reception unit provided in the measurement adapter 7 and configured to receive an operation by a user. When the input reception unit receives the operation of the user, the user detection unit 75 detects the operation of the user on the measurement adapter 7 as an operation that becomes a starting point for the user to perform the recovery operation.

As an example, the user detection unit 75 may be configured to acquire detection results of one or more sensors among a proximity sensor, an infrared sensor, an acceleration sensor, and a vibration sensor. The one or more sensors are mounted on, for example, the cover 12 or the lid 13 of the distribution board 1. The user detection unit 75 detects the opening of the cover 12 or the lid 13 of the distribution board 1 by the user as an operation that becomes a starting point of the recovery work performed by the user, based on the detection result of the one or more sensors.

As an example, the user detection unit 75 may be configured to acquire a detection result of the human detection sensor. The human body sensor is a sensor for detecting the presence of a human body using any one of infrared rays, ultrasonic waves, and electromagnetic waves, and is attached to the distribution board 1. The human sensor may be an image sensor that detects the presence of a human from a captured image. The user detection unit 75 detects an operation of the user approaching the distribution board 1 as an operation that becomes a starting point of the user performing the recovery operation, based on the detection result of the human detection sensor.

When the user carries the information terminal 400A, the user detection unit 75 may detect an operation of the user approaching the distribution board 1 based on a communication result of the communication between the measurement adapter 7 and the information terminal 400A via the remote notification unit 73A. Further, the user detection unit 75 may detect the approach of the user to the distribution board 1 based on the reception of the radio wave transmitted from the information terminal 400A by the remote notification unit 73A. In these cases, the user detection unit 75 may detect that the user approaches the distribution board 1 as an operation that becomes a starting point of the recovery work performed by the user only in a state where the application program for the monitoring system 100A installed in the information terminal 400A is activated. In addition, the user detection unit 75 may detect an operation of the user starting the application program for the monitoring system 100A as an operation that becomes a starting point of the recovery operation performed by the user.

(3) Movement of

Next, the operation of the monitoring system 100A according to the present embodiment will be described with reference to fig. 7. In the following description, it is assumed that the user detection unit 75 detects an operation of the user (person) approaching the distribution board 1 as an operation that becomes a starting point of the recovery work performed by the user based on the detection result of the person detection sensor.

First, the detection unit 712A detects the occurrence of an event related to the circuit connected to the distribution board 1 (S11). Here, if the event is that any of the circuit breakers 2 has performed a breaking operation (that is, a power failure has occurred) (S12: "yes"), the monitoring system 100A (control unit 71) raises a power failure occurrence flag (S13). On the other hand, if the occurred event is not the occurrence of a power outage (S12: NO), the presentation section 713A presents recommendation information (S19). As an example, it is assumed that the event that occurs is a time when it is necessary to replace one of the circuit breakers 2 with a new circuit breaker. In this case, the presentation part 713A transmits information that urges the replacement of the circuit breaker 2 with a new circuit breaker as recommendation information to the information terminal 400A via the remote notification part 73A.

In the monitoring system 100A, the human detection sensor detects whether or not there is a human in the periphery of the distribution board 1 (S14). When the presence of a person is detected by the person detection sensor (S14: yes) and the power failure occurrence flag is raised (S15: yes), the user detection unit 75 detects that the user approaches the switchboard 1 as an operation that becomes a starting point for the user to perform a recovery operation. On the other hand, if the human detection sensor does not detect the presence of a human (S14: "no"), or if the human detection sensor detects the presence of a human but the power failure occurrence flag is not raised (S15: "no"), the user detection unit 75 does not detect an operation that becomes the starting point of the recovery operation performed by the user.

When the user detection unit 75 detects an operation that becomes a starting point of the recovery job performed by the user, the presentation unit 713A presents confirmation information (S16). Then, when determination section 714 determines that the user has performed the step of security confirmation after presenting the confirmation information (S17: YES), presentation section 713A next presents the resume information (S18). On the other hand, if determination unit 714 does not determine that the user has performed the step of safety confirmation (S17: NO), presentation unit 713A continues to present confirmation information until determination unit 714 determines that the user has performed the step of safety confirmation (S16).

As described above, in the present embodiment, when an event related to a circuit connected to the distribution board 1 occurs, the presentation unit 713A presents recommendation information related to an action to be taken by the user in accordance with the event. Therefore, the user can know what action should be taken with respect to the occurred event by confirming the recommendation information. For example, when the event is the occurrence of a power outage, the user can perform a recovery job by confirming the recovery information (recommendation information), without having to personally investigate the procedure of recovering from the power outage. Further, for example, when it is time to replace the circuit breaker 2 with a new one, the user can replace the circuit breaker 2 before the circuit breaker 2 has a certain trouble by checking the recommendation information. That is, the present embodiment has an advantage that usability of the user can be improved.

(4) Modification example

The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be variously modified according to design and the like as long as the object of the cost disclosure can be achieved. The same functions as those of the monitoring system 100A can be realized by a monitoring method, a (computer) program, a non-transitory recording medium in which a program is recorded, or the like.

In the monitoring method according to one embodiment, occurrence of an event related to a circuit connected to the distribution board 1 is detected, and when the occurrence of the event is detected, recommendation information related to an action to be taken by a user in accordance with the event is presented.

A (computer) program according to one embodiment is a program for causing a computer system to execute the monitoring method described above.

Next, modifications of the above embodiment will be described. The modifications described below can be applied in appropriate combinations.

The monitoring system 100A in the present disclosure includes a computer system in the probe 712A or the like, for example. The computer system has a main structure of a processor and a memory as hardware. The functions as the monitoring system 100A in the present disclosure are realized by executing a program recorded in a memory of a computer system by a processor. The program may be recorded in advance in a memory of the computer system, may be provided through an electric communication line, or may be provided by recording in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive readable by the computer system. A processor of a computer system is constituted by one or more electronic circuits including a semiconductor Integrated Circuit (IC) or a large scale integrated circuit (LSI). The term "integrated circuit such as an IC or an LSI" as used herein includes integrated circuits called system LSI, VLSI, or ULSI, which are called "systems LSI" or "ULSI", depending on the degree of integration. Furthermore, an FPGA programmed after LSI manufacturing or a logic device capable of reconstructing a bonding relationship inside LSI or reconstructing circuit division inside LSI can also be used as a processor. The plurality of electronic circuits may be integrated on one chip or may be dispersed over a plurality of chips. The plurality of chips may be integrated in one device or may be distributed among a plurality of devices. A computer system as referred to herein includes a microcontroller having more than one processor and more than one memory. Thus, the microcontroller is also constituted by one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Note that the integration of a plurality of functions in the monitoring system 100A into one housing (measurement adapter 7) is not essential to the monitoring system 100A, and the components of the monitoring system 100A may be distributed among a plurality of housings. Further, the functions of at least a part of the monitoring system 100A, such as the detection unit 712A, may be realized by, for example, cloud (cloud computing). Conversely, as in the above-described embodiment, all the functions of the monitoring system 100A may be integrated into one housing (measurement adapter 7).

In the above-described embodiment, for example, as shown in fig. 8, the measurement adapter 7 may not include the remote notification unit 73A. That is, the monitoring system 100A may not have a communication function for communicating with the management server 300 and the information terminal 400A via the wide area network 200 such as the internet. In this manner, the recommendation information and the confirmation information are presented to the user only through the distribution board 1.

In the above-described embodiment, the recommendation information, the confirmation information, the cause of the power failure, and the like may be stored outside the distribution board 1, not in the storage unit 74 of the distribution board 1. For example, when the detection unit 712A detects the occurrence of a power failure due to the disconnection operation of the circuit breaker 2 as an event, the monitoring system 100A may transmit the cause of the power failure and the like to the management server 300 via the remote notification unit 73A and store the cause in the storage unit included in the management server 300. In this embodiment, for example, when the user detection unit 75 detects an operation that becomes a starting point of a recovery job performed by the user, the monitoring system 100A acquires recommendation information and confirmation information corresponding to the cause of the power outage by making an inquiry to the management server 300 via the remote notification unit 73A. In this embodiment, since the management server 300 is located outside the facility 500, even when the area including the facility 500 has a power failure, the management server 300 is less likely to be affected by the power failure, and the management server 300 can store the recommendation information and the like without being affected by the power failure.

In the above-described embodiment, when the detection unit 712A detects the occurrence of a power outage as an event, the monitoring system 100A may transmit the cause of the power outage and the like to the information terminal 400A via the remote notification unit 73A and store the cause and the like in the storage unit included in the information terminal 400A. In this embodiment, the user can obtain recommended information and confirmation information corresponding to the cause of the power outage by, for example, starting an application program for the monitoring system 100A installed in the information terminal 400A. In this embodiment, since the information terminal 400A is operated by receiving power from a built-in battery, even when a power failure occurs in an area including the facility 500, the information terminal 400A has a low possibility of being affected by the power failure, and the information terminal 400A can store recommendation information and the like without being affected by the power failure.

In the above-described embodiment, the "event" may include a time when the outlet 22 or the

electrical devices

23 and 24 needs to be replaced with a new outlet or electrical device due to the aged deterioration of the outlet 22 or the

electrical devices

23 and 24.

In the above-described embodiment, the presentation unit 713A may present the fixed sentence as the resume information. The fixed term is preferably a list of procedures for recovering from a power failure due to each cutting cause of the circuit breaker 2. Similarly, the presentation unit 713A may present the fixed sentence as the confirmation information. The fixed term is preferably a list of procedures for safety confirmation of each cutting cause of the circuit breaker 2.

In the above-described embodiment, the confirmation information may include a power plug that urges the

electrical device

23 or 24, which causes the cutting operation of the circuit breaker 2, to be pulled out from the receptacle 22. The confirmation information may include information urging the electrical engineering service provider to contact the branch breaker 4 to which the

electrical equipment

23, 24 causing the breaking operation of the circuit breaker 2 is connected. In addition, the confirmation information may further include a notification of the state of power supply to the facility 500 to the user and a prompt for a standby.

In the above-described embodiment, the procedure of the safety check (that is, the check information) may be different depending on the cause of the power failure. For example, when a power failure occurs due to a leak, the presentation unit 713A may present, as the confirmation information, a message urging confirmation of whether or not the

electrical equipment

23, 24 such as the washing machine is connected to the ground. Further, for example, when power failure occurs due to an earthquake, the presentation unit 713A may present, as the confirmation information, a message urging confirmation of whether or not a combustible material such as a curtain has come into contact with a heat source device such as a heating device.

In the above-described embodiment, the presentation unit 713A may change the content of information to be presented according to the number of occurrences of an event. For example, the presentation unit 713A may present the restoration information at a point in time when a certain circuit breaker 2 has performed the cutting operation for the first time, and present the intention of urging the circuit breaker 2 to be replaced with a new circuit breaker in place of the restoration information when the number of cutting operations exceeds a predetermined number of times.

In the above-described embodiment, the detection unit 712A may estimate the cause of the cutting operation of the circuit breaker 2 (that is, the cause of the power failure) using, for example, a learning-completed model obtained by machine learning. Further, the learning completion model used by the detection part 712A can perform relearning during use of the monitoring system 100A.

In the above-described embodiment, in a mode in which the recommendation information (restoration information) and the confirmation information are presented on the display device, the display device may be a touch panel type display. In this embodiment, the determination unit 714 may determine that the user has performed the security check step when the user touches the display. In addition, determination unit 714 may determine that the user has performed the security confirmation procedure, for example, by acquiring an affirmative message indicating the user with a microphone provided in switchboard 1.

In the above-described embodiment, the detection unit 712A may detect, as an event, a wiring abnormality of the wiring C11 (see fig. 9A and 9B) in the circuit connected to the distribution board 1. The "wiring abnormality" referred to in the present disclosure may include an abnormality such as insulation deterioration or half-disconnection in the wiring C11 included in the circuit. The term "half-broken" as used herein means a state in which a broken wire starts to occur, and specifically, if the wiring C11 is a twisted wire, the "half-broken" means a state in which some of a plurality of wires constituting the twisted wire are broken. As an example, the wiring abnormality includes the following cases: when the wiring C11 is formed of a pair of electric wires, an arc (so-called parallel arc) is generated due to a short circuit between both the pair of electric wires. Further, the wiring abnormality includes, as an example, the following cases: when the wiring C11 is formed of a pair of electric wires, an arc (so-called serial arc) is generated due to a half-break of one of the pair of electric wires.

In the above-described embodiment, a plurality of circuits are connected to the switchboard 1. Thus, the detection unit 712A detects a wiring abnormality in the wiring C11 for each circuit. The detection unit 712A detects a wiring abnormality of the wiring C11 based on the current flowing through the circuit. In the above-described embodiment, the probe 712A is provided in the measurement adapter 7. Then, the measurement adapter 7 acquires the current value measured by the current measuring device 8 as described above. Therefore, in the detection unit 712A, the wiring abnormality of the wiring C11 included in each circuit can be detected based on the current flowing through each circuit of the plurality of circuits. The detailed information about the wiring abnormality of the wiring C11 detected by the detecting unit 712A is stored in the storage unit 74.

In the above-described embodiment, the detection unit 712A can detect the occurrence of an arc as a wiring abnormality of the wiring C11. Specifically, the detection unit 712A can determine whether or not an Arc is generated in the wiring C11 by the same technique as an Arc Fault Circuit Interrupter (AFCI). That is, in the arc short-circuit protection disconnector, the current characteristics and the voltage characteristics specific to the arc generated in the wiring C11 are recognized using an electronic circuit, and the arc generated in the wiring C11 can be detected. Based on the same principle, the detection unit 712A can determine whether or not an arc has occurred in the wiring C11.

Here, as already described, there are two types of arcs that may occur in the wiring C11, namely, a parallel arc and a serial arc.

For example, as shown in fig. 9A, a short circuit may occur due to contact between conductors of a pair of wires C10 constituting the wiring C11, and a parallel arc may occur. The arrows of the broken lines in fig. 9A indicate paths of currents flowing in the wiring C11 when the parallel arc occurs. The magnitude of the current flowing through the wiring C11 when parallel arc occurs is, for example, several tens amperes a to several hundreds amperes a. For example, the cover C12 may be damaged by the wire C11 being caught at the edge of an appliance (e.g., furniture) in the facility 500, or the wire C11 may be pinched by a metal member such as a staple, thereby causing a parallel arc. In addition, for example, an overcurrent may flow through the wiring C11, which may cause the coating C12 to melt or an animal to bite the wiring C11, thereby generating a parallel arc. In addition, parallel arcing may occur if wiring C11 is degraded by prolonged exposure to ultraviolet light.

Fig. 10A shows an example of a waveform of a current flowing through the wiring C11 when a parallel arc occurs. As shown in fig. 10A, when the parallel arc occurs, the pulse current is interrupted from flowing through the wiring C11. That is, when the parallel arc occurs, the waveform of the current flowing through the wiring C11 includes a unique pattern that appears along with the occurrence of the parallel arc. Therefore, the detector 712A can determine whether or not the parallel arc is generated in the wiring C11, for example, by comparing the waveform of the current flowing through the wiring C11 measured by the current measuring device 8 with the above-described pattern.

As shown in fig. 9B, a half-break may occur in one of the pair of wires C10 constituting the wiring C11, thereby causing a series arc. The arrows of the broken lines in fig. 9B indicate paths of currents flowing in the wiring C11 when the serial arc occurs. The magnitude of the current flowing through the wiring C11 when a serial arc occurs is several amperes a to ten and several amperes a. That is, the magnitude of the current flowing through the wiring C11 when the serial arc occurs is equal to or less than the magnitude of the current flowing through the load (for example, the electric devices 23 and 24) connected to the wiring C11 in the normal state in which no wiring abnormality occurs. For example, a series arc may be generated due to repeated bending of the wire C11 or stretching of the wire C11 with excessive force.

Fig. 10B shows an example of a waveform of a current flowing through the wiring C11 when the serial arc occurs. As shown in fig. 10B, when the serial arc occurs, a current having a high-frequency component unique to the serial arc superimposed thereon flows through the wiring C11. Therefore, the detection unit 712A can determine whether or not the series arc has occurred in the wiring C11, for example, based on the high-frequency component of the current flowing in the wiring C11 measured by the current measuring device 8.

Further, the detection unit 712A detects the occurrence of an arc based on the current flowing in the wiring C11, but is not limited thereto. For example, the detection unit 712A may detect the occurrence of an arc based on a voltage applied to a circuit connected to the switchboard 1. The detection unit 712A may detect the occurrence of an arc based on both the current flowing through the wiring C11 and the voltage applied to the circuit.

The presentation unit 713A may present information on a method of handling when the wiring abnormality of the wiring C11 is detected as recommended information. For example, the presentation unit 713A may present the following as information on the coping process: all the branch breakers 4 are first switched off, and the main breaker 3 is then switched on. The presentation unit 713A may present the power cord unplugged from all the sockets 22 as information on a coping process. The presentation unit 713A may present, as information on a coping process, a contact manner for contacting the electrical engineering carrier and a meaning for urging the electrical engineering carrier to contact.

In the above-described embodiment, the presentation unit 713A may be a reading code a1 (see fig. 11) that can be read by a reading device. The reading Device includes a solid-state image sensor such as a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor. Here, the reading device is an imaging device (camera) built in a terminal owned by the user. The reading code a1 is, for example, a QR code (registered trademark). The reading code a1 may be a two-dimensional code other than a QR code (registered trademark), a one-dimensional code such as a barcode, a three-dimensional code, or a simple character string.

For example, the reading code a1 is information that enables reading of the URL of a dedicated website. Therefore, the user can acquire the URL of the dedicated website by reading the reading code a1 with the reading device of the terminal owned by the user. The user can refer to the recommendation information by starting a general-purpose browser installed in the terminal and accessing a dedicated website.

That is, in this embodiment, the presentation unit 713A passively presents the recommendation information through a job in which the user reads the reading code a1 using the reading device, instead of actively presenting the recommendation information as in the above-described embodiment.

Here, it is preferable that the reading code a1 be attached to a position easily visible to the user. For example, the reading code a1 may be attached to a case that houses the probe 712A, that is, the case 70 of the measurement adapter 7 (see fig. 2). In this embodiment, the user can see the reading code a1 by opening the lid 13 or opening the lid 13 and the cover 12. In addition, if the measurement adapter 7 is provided outside the distribution board cabinet 10, the user can see the reading code a1 without opening the cover 13 or the like.

For example, the reading code a1 may be attached to the distribution board cabinet 10 that houses the monitoring system 100A. Specifically, for example, as shown in fig. 11, the reading code a1 may be attached to one of four corners (here, the lower right corner) of the front surface of the lid 13 of the distribution board cabinet 10. In this embodiment, the user can see the reading code a1 without opening the cover 13 or the like.

Here, as shown in fig. 11, the reading code a1 is preferably printed on a sticker a2 that can be attached to an object (here, the lid 13 of the distribution board cabinet 10). In this embodiment, the reading code a1 can be attached to the object simply by attaching the sticker a2 to a desired position on the object. Note that the label a2 printed with the reading code a1 can be distributed separately in the market. Therefore, for example, by attaching the sticker a2 on which the reading code a1 is printed to a switchboard cabinet that houses a monitoring system that does not include the presentation unit 713A, the monitoring system 100A including the presentation unit 713A can be constructed.

The reading code a1 may be attached to the object by, for example, printing directly on the object. For example, the reading code a1 may be displayed on a display device disposed in the measurement adapter 7 or a display device connected to the measurement adapter 7 after the time when the event is detected by the detector 712A.

In embodiment 1 described above, the detection unit 41 of the branch breaker 4 may function as an arc detection unit for detecting an arc. Specifically, the detection unit 41 can detect the occurrence of the parallel arc based on the current value of the current flowing in the second circuit electrically connected to the first circuit. The detection unit 41 can detect the occurrence of the serial arc based on the waveform or high-frequency component of the current flowing through the second circuit. When the detection unit 41 detects the occurrence of an arc, the branch breaker 4 breaks the circuit. Here, the first circuit is a circuit electrically connected to the main breaker, and the second circuit is a circuit electrically connected to the first circuit via the branch breaker 4.

The branch breaker 4 may further include a communication unit that can communicate with the communication unit 72 of the measurement adapter 7. In this case, the collection unit 712 can collect, as the interruption information, the detection information of the arc detection unit (detection unit 41) provided in the circuit breaker 2 (branch breaker 4) via the communication unit 72.

Note that, as the function of the arc detection unit, the detection unit 32 of the main breaker 3 may have this function in addition to the function of the detection unit 41 of the branch breaker 4. In this case, the detection unit 32 can detect the occurrence of a parallel arc based on the current value of the current flowing in the first circuit, or detect the occurrence of a serial arc based on the waveform or high-frequency component of the current flowing in the first circuit. When the occurrence of an arc is detected by the detection unit 32, the main breaker 3 breaks the circuit. The main breaker 3 may further include a communication unit that can communicate with the communication unit 72 of the measurement adapter 7. In this case, the collection unit 712 can collect, as the interruption information, the detection information of the arc detection unit (detection unit 32) provided in the circuit breaker 2 (main breaker 3) via the communication unit 72.

Further, the function of detecting the arc may not be provided by the circuit breaker 2. For example, an arc detection sensor for detecting an arc may be housed in the switchboard 1 separately from the circuit breaker 2. The arc detection sensor is configured to be able to communicate with the communication unit 72. In this case, the collecting unit 712 can collect the detection information of the arc detection sensor as the interruption information via the communication unit 72.
